[PATCH 00/15] fsi: Overall improvements and new SBE fifo driver

[Benjamin Herrenschmidt]

This series brings in a number of improvements to our FSI stack
(one of the service interfaces for communicating between a BMC chip and
our POWER processors).

The GPIO based "Soft FSI" performance is significantly improved, and
it's reliability as well.

The SBE fifo driver provides the interface to the processor "Self Boot
Engine"

Some of these patches have been simmering for a while in the OpenBMC
tree.
